Learning Outcomes

Learning outcomes

The students will acquire with the successful completion of the course

  • the skills to solve equations of small degree,
  • the skills to find splitting fields and compute Galois groups,
  • understand the problem of solving polynomial equations by radicals,
  • understand the impossibility or not of certain constructions by ruler and compass.
